"This has been a productive year for ArriVent that included strong achievement across our firmonertinib clinical programs and significant execution of our company strategy through the expansion of our ADC portfolio. The differentiated potential of firmonertinib to address classical and uncommon EGFR mutations was reinforced by the robust anti-tumor activity in NSCLC patients with EGFR PACC mutations reported at the World Conference on Lung Cancer, and the preclinical data presented at AACR (Free AACR Whitepaper)" said Bing Yao, Chairman and Chief Executive Officer of ArriVent. "We also bolstered our ADC portfolio with the recent in-licensing of ARR-217 (MRG007) and research collaboration with Alphamab, underscoring our commitment to further expand our pipeline and develop new innovative therapies to potentially treat cancer patients with unmet medical need."

Dr. Yao continued, "We have achieved our target enrollment of 375 patients in our global, pivotal Phase 3 monotherapy study of firmonertinib in first-line NSCLC patients with EGFR exon 20 insertion mutations. In addition, we plan to provide an update on our plans to investigate firmonertinib as monotherapy in first line NSCLC patients with EGFR PACC mutations in the first half of 2025. For our ADC portfolio, we selected our next-generation ADC candidate, ARR-002, for IND-enabling activities. Our focus continues to be on executing across our near-term catalysts and we are poised for an impactful year ahead."

Recent and Full Year 2024 Highlights

Firmonertinib

● Achieved target enrollment for the global pivotal Phase 3 monotherapy study of firmonertinib in first-line NSCLC EGFR exon20 insertion mutations (FURVENT; NCT05607550). Earlier this year, ArriVent reached its target enrollment in the FURVENT study. Firmonertinib, an oral, highly brain-penetrant, and broadly active mutation-selective epidermal growth factor receptor (EGFR) inhibitor, received FDA Breakthrough Therapy Designation in this patient population.
● Positive proof-of-concept data in EGFR PACC mutant NSCLC. In September 2024, ArriVent presented interim Phase 1b clinical data for first-line firmonertinib monotherapy in NSCLC patients with EGFR PACC mutations (FURTHER; NCT05364043) during the Presidential Symposium at the

2024 World Conference on Lung Cancer and hosted a virtual webinar. Firmonertinib demonstrated robust systemic and CNS anti-tumor activity with a manageable safety profile consistent with previous trials in what we believe to be the first clinical dataset testing an EGFR inhibitor in a prospectively defined population of EGFR PACC mutant NSCLC.
● Presentation of preclinical data for firmonertinib at the 2024 AACR (Free AACR Whitepaper) Annual Meeting. In April 2024, ArriVent presented data evaluating firmonertinib in preclinical models with EGFR exon 20 insertion mutations and with P-loop and alpha-c helix compressing (PACC) mutations at the AACR (Free AACR Whitepaper) Annual Meeting. In the preclinical study, firmonertinib was observed to be broadly active across a wide range of uncommon mutations including PACC and exon 20 insertion mutations.
● Initiated Phase 1b combination study with firmonertinib and SHP2 allosteric inhibitor ICP-189. In March 2024, ArriVent’s clinical collaboration partner Beijing InnoCare Pharma Tech Co., Ltd., dosed the first patient in the Phase 1b combination study targeting advanced or metastatic NSCLC patients with EGFR classical mutations.
Pipeline

● Added ARR-217 (MRG007) to our pipeline from Lepu Biopharma. In January 2025, ArriVent entered into a collaboration with Lepu Biopharma Co., Ltd. for ARR-217, an ADC with the potential to target several GI cancers. Under the agreement, ArriVent obtained the exclusive rights to develop and commercialize ARR-217 worldwide outside of greater China, which includes mainland China, Hong Kong, Macau and Taiwan.
● Selected a next-generation antibody drug conjugate (ADC) candidate. In late 2024, ArriVent and its partner, Aarvik Therapeutics, Inc., selected a multi-target multivalent ADC candidate, ARR-002, for the treatment of solid tumors. ArriVent has initiated IND-enabling studies for ARR-002.
● Entered into an ADC collaboration agreement with Alphamab. In June 2024, ArriVent entered into a collaboration agreement with Jiangsu Alphamab Biopharmaceuticals Co., Ltd. (Alphamab), a wholly owned subsidiary of Alphamab Oncology, to discover, develop and commercialize novel ADCs for the treatment of cancers. Under the agreement, both companies leverage Alphamab’s proprietary linker-payload platform and glycan-conjugation technology to identify novel ADCs for oncology indications. The collaboration agreement grants ArriVent exclusive rights to develop and commercialize ADCs globally, except greater China, which includes mainland China, Hong Kong, Macau and Taiwan.
Upcoming Milestones

● EGFR PACC plans. Data from the FURTHER Phase 1b (NCT05364043) trial continues to mature for first-line firmonertinib monotherapy in NSCLC patients with EGFR PACC mutations. ArriVent expects to provide an update on our plans to develop firmonertinib in EGFR PACC mutant NSCLC in the first half of 2025.

● First IND Filing for ADC Program. ArriVent and its partner, Lepu BioPharma, plan to file the first IND for ARR-217 in the first half of 2025.

● Top-line pivotal Phase 3 data. Firmonertinib has reached its target enrollment in the FURVENT study. ArriVent anticipates having top-line data in 2025 and expects to provide an update on timing of the top-line Phase 3 data release in Q2 2025.
2024 Financial Results

● As of December 31, 2024, the Company had cash, cash equivalents, and short and long-term investments of $266.5 million, which is expected to fund operations into 2026. Net cash used in operations was $70.2 million and $55.8 million for the years ended December 31, 2024 and 2023, respectively. During 2024, ArriVent completed an IPO raising net proceeds of $183.2 million, after deducting underwriting discounts, commissions, and other offering expenses.

● Research and development expenses were $79.0 million and $64.9 million for the years ended December 31, 2024 and 2023, respectively. The increase in expense was primarily due to increased headcount and clinical expense related to firmonertinib.

● General and administrative expenses were $15.3 million and $9.7 million for the years ended December 31, 2024 and 2023, respectively. The increase in expense was primarily due to expenses related to expanding the infrastructure necessary for operating as a public company.

● Net loss was $80.5 million and $69.3 million for the years ended December 31, 2024 and 2023, respectively.
